I thought Acans ARE AGGRESSIVE!!!

[kmjoen230]

Guess not :(
Last month I bought some Acans, nice sized colonys, 8-10 polyps each and places them in a place that I thought was a low flow lower light area.
It was night time when I placed them in my tank.
The next morning I spotted a Large Red mushroom that was kind of encroaching the red colony i got(pics below) that I had not noticed when I placed them in the tank, but I thought eh its a large ugly red Shroom that i really don't care about and it looked like the acans were not too bothered by it, but the shroom looked all crippled.
I came home from work, everything was fine, the acans were a little sucked in around the shroom but I ws confident that they would kill the shroom. That night, when the shroom sucked in, the heads of the acan were polyped out and so I fed em some cyclopeez.
Here are the pics of them being healthy...

WTF!?

[Blownsvt]

what else is in the tank? a shroom wouldn't do that would it?

[kmjoen230]

It is exactly what did it.
See the Green Acan behind the Red?
The Green is fine. The Red was only affected in the area the shroom was touched...
Needless to say, i erradicated all form of shroom in my tank.

I had a ricordia do the same thing to one of my acan colonies. Both back to normal in a month.

health of the coral will play a role on aggressiveness.

Sorry, I was just really hungry and that coral looked tasty!:gay1:

But on a serious note, thanks for the advice, I've never actually had my mushrooms sting anything, but its interesting that they could. My yuma is touching some palys and a few of my palys and shrooms sometimes touch my open brain, I'll move them a bit.

Just be careful, that almost looks a little bit like brown jelly disease. As a precaution I would dip'em and put him in med. flow and low light for now. I had one come in(online order) looking like that and lost the whole colony within a week:coolmad: (I did get a full refund though)

I didn't think a shroom would irritate another coral either...that is until I stuck a candy cane coral in between two of them in a hole in my live rock. One of the shrooms didn't like it very much and these curly white strings came out of its mouth and stung (or digested) two heads of the candy cane. It really set them back.

The strange thing with my situation is that the mouth of the mushroom was not near the head of the acan, it was just touching each other side by side.
Thanks everyone for your input and experience.
Wish me luck in getting it back to health!

I had a mushroom burn a hole on the edge of an echino . Healed back in a couple of weeks.

:biggthumpup::biggthumpup: I second that.
